Made a tin whistle to learn and practice without annoying my neighbors. It doesn't take much filament to print and does sound fairly clean.

I think it could also be nice for beginners, since it has small flat holes that are easy to cover and it takes very little air to play.

Also made a version for people who have A1 mini printer https://makerworld.com/models/2099264
